Paper Title:
Brazilian Raw Materials Doped TiO2 Based Electroceramics
  Abstract

Dopants such as Ta2O5 play a major role in the formation of barriers at the grain boundary in TiO2 varistors, increasing their nonlinear coefficient and decreasing their breakdown electric field. This paper discusses the microstructural and physical properties of Ta- and Cr-doped TiO2 systems in which imported tantalum oxide was replaced with an equivalent Brazilian raw material. Preliminary results confirm that this national oxide can be utilized to obtain electroceramics such as varistors.
